The preoperative conventional tomographic and Magnetic Resonance images were reviewed of 81 patients affected with bronchogenic carcinoma; all patients underwent surgery 1986 to 1988. Radiological findings were compared with surgical and pathological results to evaluate the actual role of conventional tomography in the staging of bronchogenic carcinoma. MR Imaging proved to be more useful in the evaluation of mediastinal and hilar lymph nodes. As for mediastinal node status, conventional tomography had 23.5% sensitivity, 90.6% specificity, and 76.5% overall accuracy; MR Imaging had 82.3% sensitivity, 84.4% specificity, and 84% overall accuracy. As for hilar adenopathies, tomographic sensitivity, specificity and overall accuracy were 53.3%, 72.5%, and 65.4% versus 50%, 82.3% and 70.4% with MR Imaging. Tomography was slightly superior in identifying the primary tumor (97.5% versus 92.6% for MR), as well as in the demonstration of central bronchial involvement (100% for conventional tomography versus 50% for MR Imaging). Conventional tomography is useful as a complementary technique to MR Imaging in the preoperative staging of bronchogenic carcinoma when information on central bronchial involvement is needed.
回顾了81例支气管源性癌患者术前的传统断层扫描和磁共振成像；所有患者在1986年至1988年期间接受了手术。将放射学检查结果与手术和病理结果进行比较，以评估传统断层扫描在支气管源性癌分期中的实际作用。磁共振成像在评估纵隔和肺门淋巴结方面被证明更有用。对于纵隔淋巴结状态，传统断层扫描的敏感性为23.5%，特异性为90.6%，总体准确率为76.5%；磁共振成像的敏感性为82.3%，特异性为84.4%，总体准确率为84%。对于肺门淋巴结肿大，断层扫描的敏感性、特异性和总体准确率分别为53.3%、72.5%和65.4%，而磁共振成像分别为50%、82.3%和70.4%。在识别原发性肿瘤方面（传统断层扫描为97.5%，磁共振成像为92.6%）以及在显示中央支气管受累方面（传统断层扫描为100%，磁共振成像为50%），断层扫描略占优势。当需要有关中央支气管受累的信息时，传统断层扫描作为磁共振成像的补充技术在支气管源性癌的术前分期中是有用的。
